Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a mower in the lower abdomen of a passenger vehicle body at an intermediate position between the front and rear, and a control seat provided in the upper part of the vehicle body at an intermediate position between the front and rear of the passenger vehicle body. Also, a low cylindrical grass collecting container is installed at the rear of the passenger vehicle body and located below and behind the operator seat,
The grass collection container is provided with an opening for discharging cut grass facing toward the front, and a front wall is provided at the opening of the grass collection container to prevent stored grass from falling out and to allow ventilation. A turf inlet is opened at an intermediate point in the vertical direction of the front wall, and an air vent is formed in each of the upper and lower parts of the turf inlet in the front wall, so that air can be removed from the mower. A riding type lawn mower provided with a discharge duct for guiding the cut grass to the grass input port.

[Conventional technology]

Conventionally, for riding lawn mowers, for example,
As disclosed in Japanese Patent No. 60-94037, there is known a structure in which a grass collection container at the rear of the vehicle body has an opening at the top. With this configuration, the lifting height when lifting the grass clippings from the mower to the grass collecting container becomes large, resulting in a large burden of power required for lifting the grass clippings.

[Problem to be solved by the invention]

To resolve this inconvenience, it is possible to reduce the lifting height from the mower to the grass container by, for example, providing the grass clippings inlet on the front side of the grass container. In some cases, the cut grass inlet and the air vent are formed on the entire surface of the bottomed cylindrical grass collection container, which is the opening for discharging the cut grass. There is a sanitary problem in that dust and the like blown toward the vehicle body and carried by the exhaust air from the grass container tend to float around the driver riding on the vehicle body, deteriorating the working environment for the driver.

The present invention has been made in view of the above-mentioned circumstances, and uses simple structural modifications to reduce the power burden in transporting grass clippings while also preventing air from being discharged from the grass collection container toward the driver. The purpose is to provide a riding lawn mower that can.

[Means to solve the problem]

In order to achieve the above object, the riding lawn mower according to the present invention has the above-mentioned structure, and has an exhaust guide that guides the exhaust air from the air vent located above the grass inlet to the lower side. The body is provided with the lower end edge of the air exhaust guide body extending downward from the operator seat, and the air vent located below the grass input port is provided facing the lower side of the passenger vehicle body. The characteristic configuration is that it is provided in a state where the

The functions and effects of this characteristic configuration are as follows.

[Effect]

In other words, although the opening of the grass collection container is directed toward the front of the machine and air is vented to the front, by providing an exhaust guide, air can be removed from the air vent located above the grass input port. The exhaust air is guided downward, and the exhaust air guided downward also causes the exhaust air from the air vent located below the grass input port to flow downward. Furthermore, since the lower edge of the wind exhaust guide extends downward from the driver's seat, the exhaust air from the grass collection container is blown to the lower part of the vehicle body that is further away from the driver's seat. This will prevent dust from floating near the seat due to the exhaust air from the grass collection container.

[Effects of the Invention] Therefore, by simply modifying the air exhaust guide by installing an air exhaust guide opposite to the air vent located above the turf inlet, air vents located above and below the turf inlet can be installed. The exhaust air from the air bleeder is flowed to the lower part of the vehicle body, which is further away from the pilot's seat, so that dust, straw, etc. carried by the exhaust air will not fall on the passenger, and dust, etc. will be scattered around the passenger. The present invention has resulted in a riding-type lawn mower that can suppress floating, avoid causing discomfort to the rider, and maintain good hygiene in the vicinity of the operator's seat.

〔Example〕

As shown in FIG. 5, a driving unit E and a fuel tank 1 are provided on the front side of the passenger vehicle body V, a control handle H is provided in the center of the passenger vehicle body V, and a seat 2 as a pilot seat is provided on the rear side of the passenger vehicle body V. A mower M having a cutting blade rotatable around a vertical axis is provided in the lower abdomen of the passenger vehicle body V, and a pair of left and right running wheels 3 and 4 are provided on the front and rear sides of the mower M, respectively. , and a bottomed cylindrical grass collection container A that stores the cut grass supplied from the mower M through the discharge duct 5 by the wind generated by the rotation of the cutting blade.
is connected to the rear of the passenger vehicle body V to constitute a riding type lawn mower.

In configuring the grass collection container A, FIGS.
As shown in the figure, a ventilation-permeable front wall 7 is provided in the grass discharge opening provided on the front side of the grass collection container A to prevent stored grass from spilling out, and a vertically midway point of this front wall 7 is provided. A turf inlet 7a is opened in which the discharge duct 5 can be inserted and removed.

Further, an air vent 7 is provided in each of the upper and lower parts of the grass input port 7a in the front wall 7.
b, 7c, and the grass input port 7a.
As shown in FIG. 5, the exhaust guide body 8 that guides the exhaust air from the air vent 7b located on the upper side to the lower side covers the upper part of the grass input port 7a, and as shown in FIG. It is integrally formed with the front wall 7 with its lower edge positioned below the seat 2, thereby suppressing the exhaust air from the air vents 7b and 7c from being discharged to the front side. .

The front wall 7 is swingably attached to the front opening of the grass collection container A so that it can be opened when discharging grass as described later.

To explain the mounting structure of the grass collecting container A, a rail 10 fixed with a pin is provided to a U-shaped bracket 9 extending from the vehicle body side.
A pair of pins P _{1 and} P ₂ guided along the grass collecting container A are provided on the side wall a of the grass collecting container A.
is supported so as to be able to move in parallel for insertion into and removal from the discharge duct 5, and to be swingable for changing the posture.

Note that a roller 11 is externally fitted onto one pin _P2 of the pair of pins _P1 and _P2 .

Next, the grass collection container A is connected to both the pins P ₁ and P _{2 .}
The operation of swinging the control lever 12 between the upward and downward postures by operating the operating lever 12 that is externally supported by the device will be described.

First, the grass collecting container A in the fallen position is moved in parallel to the rear side and removed from the discharge duct 5, and then the engaging recess 1 formed on the lower side of the rail 10
By engaging the roller 11 with the pin 3, the flexible part 14 formed on the upper side of the rail 10 is connected to the pin
Now that P ₁ is movable, the operating lever 12
By swinging the grass container A downward, the grass collecting container A is pivoted to an upward position around the positioned pin _P2 of the roller 11.

Then, by further swinging the operating lever 12 downward, the grass collecting container A is swinged into a downward position.

In addition, numeral 15 in the figure is a protrusion for receiving a pin for preventing the grass collecting container A from moving upward when the grass collecting container A is swung to a downward position.
